I send following data to Logstash:

```auto
{
"a": 1,
"b": 2,
"c": 3,
"d": {
      ["key": "felan", "value": 123], ["key": "bahman", "value":321]
    }
}

```

I want to convert it to:

```auto
{
"a": 1,
"b": 2,
"c": 3,
"d": {
      "felan": 123, 
      "bahman": 321
    }
}

```

How should I write the filter in Logstash?

You will need something like [this](https://discuss.elastic.co/t/solved-split-filter-question-a-k-a-flatten-json-sub-array/130481/12).
